Ok, i dont want to get my hopes up but i'm pretty sure i have a 21 pin model 1 sega saturn. I opened it up and i just want to make sure i'm counting the right pins. Say i'm looking at the saturn from the front facing me. The ribbon to the right, do i count the pins which connect that ribbon to the cd board? If not, what pins do i count. If i do count those... then i have 21 pins.
